I guess I could add some to this discussion. I still think that another part of the equation why these cars didn't sell, other than looks, price and practicality was that people generally didn't understand the reason for the wing and nose. In those days aerodynamics was rocket science for the average joe in car buying mode. About 20 yrs ago I actually drove a friends 69 Daytona, 440-6, O.D. tranny and I'm guessing 3.25 gears (real low). That monster would do 100MPH in third. At the same time I drove a 69 super bee, 440 2x4, 4 speed and even though that tank was around 4000#'s the nose would start to get lite around 120, to much air getting under the front end and not a comforting feeling. At 120 that Daytona was glued to the highway and at about 1 inch past the 150 mark it was still stuck. I do remember though that the air leaks around the doors and side windows got annoying at anything above 110MPH. What a rush.:-D
